I was told to use the 4 to 1 ratio when I got my first GBB. For every four propane filled magazines (without silicone) I used a green gas filled magazine. It worked with my WE416 without any problems and has worked on my LM4 the same. For game play I would lube the BCG before the game and load my chest rig with 4 magazines. 3 propane filled and one green gas filled. With the one magazine in the LM4 it would make a 4 to 1 ratio. I put green electrical tape on the GG magazine, red on the propane for a visual aid.

That sounds like a great, and economic way to do things. I may use that. Let me know if any problems arise in the future.

I was playing with my tornado grenade and reading this thread; I noticed some people call propane "dirty" and say that the oderant used creates a grey slime that gunks up the gun.

So while I was playing with my grenades that have never even heard of green gas, used in about 4 games with little to no maintenance done, and I could not find this grey gunk that is supposed to come from Propane. The plastic is white, so it would surely stain or at least appear on the grenade. Nothing.

So I wonder why the tornado grenades use rubber gaskets, thick silicon oil, and have polymer innards. Yet AI recommends propane for them. Aren't the materials kinda the same in grenade vs a gun? Rubber gaskets, etc etc. So why don't the Tornado grenades break after the first use of propane like some claim propane does to a gun?

Sure the guns are more complex, but I've had no problems with my impact grenade and timer grenade. It worked when I needed to flush out 5 people by myself, and it works when I play with it in my back yard consistently.

Just food for though on the GG vs Propane debate. I thought it was odd that my Grenades work perfect when they also use rubber gaskets and are super clean despite my lack of care. I thought if propane was so bad that it would have broken down the grenade by now...

I also own Tornado Grenade, I also use propane with it. When I clean my grenade innards with rags, the rags always look like I just removed black grease...

The black crud is supposed to be there... well, kind of. Propane has additives that green gas doesn't, additives that are normally burned up when used in a stove, but in an airsoft gun it doesn't burn so those additives build up in the gun. Is that crud bad for the gun? Perhaps, though we don't know for sure just how much damage it may be doing. The best thing you can do, whether you're running propane or green gas, is to break your gun down and clean it after each game day. This will ensure that the crud is not sitting on your parts and possibly deteriorating. It is a bit more of a pain to have to clean it often, but personally I enjoy it because it makes the GBB feel even more realistic. Plus, when you're cleaning it you can inspect your other parts and make sure everything is doing what it's supposed to. Lube up the moving parts and valves and reassemble, then you're good to go.

I've had my LM4 for about a week now, and I had fully anticipated using Green Gas during the warranty period, and then switch to propane after 45 days. My initial order of Green Gas was $29 and I got five 4 oz cans of Green Gas. I buy small cans so I can pack a can in my chest rig. I've shot probably 8-12 mags out of the LM4 and 5 mags out of my M9 and I'm still on my first 4oz can of Green Gas. Honestly, if the Green Gas lasts this long I'll probably just use Green Gas as long as I can. I don't shoot much and we only have a game every 2 months or so, and I can see a single can of Green Gas lasting through an entire game or more. Green Gas for me for now.

One thing I will say. My gun was very gunked up even after using Green Gas. There was a thick layer of black grease all inside the gun. If Green Gas is that bad, I can't imagine how much worse propane would be.

Another thing I was surprised at was how much I smelled the Gas. Don't know if I really want to be sniffing that much propane given the smell.
